The overall tower performance is influenced by the type of both tower internals and random packing. The Raschig GmbH's most recent development is the Raschig Super-Ring®, the fourth generation of random packings. In 1998, the Raschig Super-Ring No. 2 was tested at the facilities of Fractional Research Inc. A significantly improved capacity and pressure drop over other random packing was ...

A few years ago Union Camp turned a corner. Management decided that advance planning would take the place of reacting after the fact to an emergency or regulatory agency demands. At Union Camp’s Dover, OH. facility, byproducts of the paper industry are converted into usable specialty chemicals for cosmetics, adhesives and other industries. Crystallization is a process used intensively ...

Development of chemical industry and high vapor pressure of volatile organic compounds (VOCs) have been caused that these materials recently be considered as a source of air pollution. These are different methods for separation of VOC from air that absorption by suitable and selective solvent is an efficient method. In this research, mathematical modeling of a packed absorption tower for ...

StockPot, a Campbell's Soup subsidiary, makes premium soups, sauces, chilies and marinades for the foodservice industry. To control odors from the cooking of meats, onions and other ingredients, StockPot purchased a Tri-Mer 40,000 cfm packed bed scrubber. Tri-Mer packed towers are well-suited to the foods and flavors industries and perform at efficiencies of 99% and higher. They are ideal ...

ABSTRACTThe Orange County Sanitation District (Sanitation District), under a capital improvement project, developed an automated procedure to perform acid washing on packed tower chemical scrubbers. Packed-tower chemical scrubbers operate with an alkaline solution, composed of sodium hydroxide, an oxidant, and make-up water. The make-up water may be chlorinated secondary treated wastewater or ...

Croll-Reynolds designed the Union Camp packed tower scrubber for ammonia removal efficiency at 99+% for the minimum single valve release and well over 90% for the entire range of operation. A few years ago Union Camp turned a corner. Management decided that advance planning would take the place of reacting after the fact to an emergency or regulatory agency demands. At Union Camp's Dover, OH, ...

The problem Dry cleaning fluids have contaminated groundwater supplies in all areas of the United States. One of the most common contaminants is PCE (perchloroethylene or tetrachloroethylene, Cl2C=CCl2). As a suspected carcinogen, PCE must be removed from water to very low levels. The US EPA maximum contaminant level (MCL) for PCE in drinking water is 5 ppb (5 parts per billion, or 5 mg/L). ...

ABSTRACT Packed-tower chemical scrubbers, with sodium hydroxide (caustic) and sodium hypochlorite (bleach), are commonly used to treat foul air from wastewater treatment processes. The available control mechanisms include a pH probe and controller for the sodium hydroxide feed, an oxidation reduction potential (ORP) probe with a controller toestablish the bleach feed, and proprietary ...

A customer with a sulfuric acid reclamation facility needed to cool a saturated air stream or closed loop process operation. The 10,000 CFM air stream at 165° F. had to be cooled to 110°F. The existing equipment was only able to achieve 125°F. Cooling liquid availability included a large quantity of processed water at 110°F and a smaller amount of city water at 55°F. Verantis recommended ...

With the introduction of any new product comes questions about its limitations. The StormTank Pack is a structural sheet media solution for light-duty stormwater storage. While the usage of structural sheet media in stormwater management may seem like a new concept in North ...

This article is about the case study of the TurbeEx® Cooling Tower in operation at a Huhtamaki U.S. pulp & paper facility. Commissioned in late Spring 2016 this TurbEx® COOLING TOWER cools process water at a Huhtamaki U.S. pulp & paper facility using TurboScrubber® fluidized packing to ensure continuous non-clogging operation even with sticky pulp & solids ...

A number of sources in the wastewater treatment process such as the headworks, aeration tanks, settling tanks and dewatering press can produce high-intensity odors from gaseous sulfide emissions. The most common sulfides arehydrogen sulfide (H2S) and methyl mercaptan (CH3SH.)The highlighted installation was for a major municipality in the southeast and utilizes our new high efficiency 3-K ...

One of the simplest and most cost-effective ways in which to extend the life of a cooling tower, improve heat transfer efficiency and reduce maintenance downtime, is to upgrade the cooling tower’s fill media to components constructed out of robust and non-clogging materials such as Polypropylene (PP), PVC or stainless steel. Fill is a critical component in the heat transfer ...

G&G Orchards in Yakima is the only Hispanic-owned packing house in Washington. Today, that operation includes some 800 acres of orchards, a packing house, and a controlled atmosphere cold storage facility. They also produce late season cherries in the most sought after varieties. They wished to remove and prevent limescale in their cooling tower and to reduce their use of chemicals. A P120 ...
